playwright-screen-recordingRecords headless Playwright sessions as .webm videos to show a bug fix working or to give pull request reviewers visual evidence.
Playwright's built-in video recording captures a headless browser session as a .webm file (VP8), which can be attached to a pull request or used to prove a bug fix. The skill shows the pattern with the Python sync API and suggests recording before and after states, regression paths and other interactions that would otherwise be described in words.
Practical tips cover adding short pauses between actions, about 800 milliseconds in the example, so viewers can see each click; printing expected and actual state to the terminal alongside the video as a second check; and building demo pages from real trace data rather than synthetic data.
Each page produces its own video file, record_video_size sets the resolution and should match the viewport, recording works without a display, and files are typically a few hundred KB, small enough to attach to a PR or chat message.
Read from SKILL.md and the folder at commit 4cc867d. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

Playwright Screen Recording loads about 714 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 159 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
